Medicare covers some dementia care, but not all of it, and the coverage depends on which part of Medicare you have and what type of care you need

Medicare Part A covers inpatient hospital care and skilled nursing facility stays if a doctor says you need them after a hospital stay. If you have dementia and need short-term skilled care — physical therapy, wound care, or nursing supervision — after a hospital admission, Part A will cover up to 100 days in a skilled nursing facility. Medicare Part B covers doctor visits, mental health counseling, and certain diagnostic tests like brain imaging if your doctor orders them to evaluate memory loss or cognitive changes.

Medicare Part B also covers psychiatric services and neuropsychological testing when ordered by a doctor. However, Medicare does not cover long-term custodial care — the day-to-day help with bathing, dressing, eating, and toileting that many people with dementia eventually need. It also does not cover assisted living facilities, memory care units, or in-home personal care aides unless that care is part of a covered skilled nursing or home health service.

Key Takeaways

  • Medicare Part A covers up to 100 days in a skilled nursing facility after a hospital stay, but only if the care is skilled nursing or rehabilitation, not custodial care.
  • Medicare Part B covers doctor visits, mental health counseling, and diagnostic imaging to evaluate cognitive changes, but not ongoing personal care or supervision.
  • Medicare does not cover assisted living, memory care units, or long-term custodial care in any setting.
  • Medigap and Medicare Advantage plans may offer additional coverage for some services, but the details vary by plan.
  • Medicaid, not Medicare, is the primary payer for long-term custodial care and assisted living in most states.

What Medicare Part A Covers for Dementia

Medicare Part A covers a hospital stay if you are admitted for a condition related to dementia — such as a fall, infection, or acute confusion — and your doctor determines you need inpatient care. After discharge, Part A will pay for up to 100 days in a Medicare-certified skilled nursing facility if your doctor orders skilled care. Skilled care means nursing services, physical therapy, occupational therapy, or speech therapy provided by licensed professionals. The facility must be certified by Medicare, and you must have been hospitalized for at least three consecutive days before the stay begins.

During the first 20 days, Medicare Part A covers the full cost of the skilled nursing facility. From day 21 to day 100, you pay a daily coinsurance amount (the amount changes each year). After 100 days, Medicare stops paying, and you or your family must cover the cost or transition to another payment source. This coverage is temporary and is meant for recovery or rehabilitation, not permanent placement.

What Medicare Part B Covers for Dementia Evaluation and Mental Health

Medicare Part B covers visits to your primary care doctor, neurologist, or psychiatrist to evaluate memory loss or cognitive decline. If your doctor orders diagnostic tests — such as a CT scan, MRI, or PET scan of the brain — Part B will cover 80 percent of the cost after you meet your annual deductible. Neuropsychological testing, which is a detailed assessment of memory, thinking, and behavior, is also covered when ordered by a doctor.

Part B also covers mental health counseling and psychiatric services. If you have dementia and develop depression, anxiety, or behavioral problems, you can see a psychiatrist, psychologist, or licensed clinical social worker, and Medicare will cover 80 percent of the cost after your deductible. These services may be provided in a doctor's office, clinic, or hospital outpatient setting. However, Medicare does not cover long-term supervision, monitoring, or personal care — only the medical evaluation and treatment of the condition itself.

What Medicare Does Not Cover

Medicare does not cover custodial care, which is help with activities of daily living such as bathing, dressing, eating, toileting, and grooming. Even if you have dementia and cannot perform these tasks safely, Medicare will not pay for a personal care aide, home health aide, or facility staff to provide this care unless it is part of a covered skilled nursing or home health service. Once skilled care ends, custodial care is no longer covered.

Medicare does not cover assisted living facilities or memory care units, even if they are licensed and provide 24-hour supervision. These settings are considered residential, not medical, and Medicare does not pay for room and board or supervision. Long-term nursing home care is also not covered by Medicare, except for the first 100 days after a may have access to hospital stay. Adult day care programs, respite care, and in-home supervision are not covered by Medicare.

Medicare Advantage and Medigap: Additional Coverage Options

If you have a Medicare Advantage plan (Part C), the plan may offer coverage for some services that Original Medicare does not, such as adult day care, respite care, or additional mental health services. However, coverage varies widely by plan and by state. You should review your plan's summary of coverage or call the plan directly to ask what dementia-related services are covered beyond what Original Medicare provides.

If you have a Medigap (supplemental insurance) plan, it covers some of the costs that Original Medicare does not pay — such as coinsurance and deductibles — but it does not add new services. Medigap does not cover custodial care, assisted living, or long-term care. Neither Medicare Advantage nor Medigap replaces the need for Medicaid or long-term care insurance if you need extended custodial care.

When Medicaid Becomes the Primary Payer

Medicaid, not Medicare, is the program that covers long-term custodial care, assisted living, and memory care in most states. Medicaid is a joint federal and state program for people with low income and limited assets. If you need ongoing help with daily activities due to dementia, Medicaid may cover the cost of a nursing home, assisted living facility, or in-home personal care, depending on your state's rules and your financial situation.

To understand what Medicaid covers in your state, contact your state Medicaid office or a local Area Agency on Aging. The rules for income and asset limits vary by state, and some states have waiting lists for certain services. If you are concerned about future care costs, you may also want to explore long-term care insurance, which is a separate private insurance product that covers custodial care and is not part of Medicare or Medicaid.

Medicare Home Health Coverage for Dementia

Medicare Part A and Part B together cover home health services if your doctor orders them and you are homebound or have difficulty leaving home. Home health can include skilled nursing, physical therapy, occupational therapy, and speech therapy. A home health aide may also visit to help with personal care, but only if the aide's visits are part of a skilled nursing or therapy plan and are supervised by a nurse or therapist.

Home health coverage is temporary and is meant to support recovery or maintain function while you receive skilled services. Once the skilled need ends, the home health aide visits stop, and Medicare will not pay for ongoing personal care in the home. If you need long-term in-home help with daily activities, you will need to pay out of pocket, use Medicaid (if you may have access to), or arrange private pay care.

Frequently Asked Questions

Does Medicare cover memory care or assisted living?

No. Medicare does not cover assisted living facilities, memory care units, or any residential setting where the primary service is supervision and help with daily activities. These are considered custodial care, not medical care. Medicaid may cover assisted living in some states, depending on your income and assets.

Will Medicare pay for a home health aide to help my parent with dementia bathe and dress?

Only if a nurse or therapist is also visiting to provide skilled care, and the aide's visits are part of that skilled plan. Once the skilled care ends, Medicare stops paying for the aide. If your parent needs ongoing personal care, you will need to pay privately, use Medicaid, or arrange care through another source.

Does Medicare cover neuropsychological testing for dementia?

Yes, if a doctor orders it. Medicare Part B covers neuropsychological testing — detailed testing of memory, thinking, and behavior — when ordered by a physician to evaluate cognitive decline. You pay 20 percent of the cost after you meet your annual deductible.

What happens after 100 days in a skilled nursing facility?

Medicare stops paying after 100 days. If you still need care, you or your family must pay out of pocket, transition to Medicaid (if you may have access to), or move to another setting. Some people return home with family care or home health services; others remain in the facility and pay privately.

Does my Medicare Advantage plan cover more dementia care than Original Medicare?

It may. Some Medicare Advantage plans offer additional services such as adult day care, respite care, or extra mental health visits. You should review your plan's coverage document or call the plan to ask what dementia-related services are included beyond what Original Medicare covers.
